Subsumption Testing

OPERATION: Subsumption Testing

The official URL for this operation definition is:

http://hl7.org/fhir/OperationDefinition/CodeSystem-subsumes

Test the subsumption relationship between code/Coding A and code/Coding B given the semantics of subsumption in the underlying code system (see hierarchyMeaning).

When invoking this operation, a client SHALL provide both a and codes, either as code or Coding parameters. The system parameter is required unless the operation is invoked on an instance of a code system resource. Other parameters are optional

Documentation

IN

codeA

0..1

code

The "A" code that is to be tested. If a code is provided, a system must be provided

IN

codeB

0..1

code

The "B" code that is to be tested. If a code is provided, a system must be provided

IN

system

0..1

uri

The code system in which subsumption testing is to be performed. This must be provided unless the operation is invoked on a code system instance

IN

version

0..1

string

The version of the code system, if one was provided in the source data

IN

codingA

0..1

Coding

The "A" Coding that is to be tested. The code system does not have to match the specified subsumption code system, but the relationships between the code systems must be well established

IN

codingB

0..1

Coding

The "B" Coding that is to be tested. The code system does not have to match the specified subsumption code system, but the relationships between the code systems must be well established

OUT

outcome

1..1

code

http://hl7.org/fhir/ValueSet/concept-subsumption-outcome|4.5.0 (Required)

The subsumption relationship between code/Coding "A" and code/Coding "B". There are 4 possible codes to be returned (equivalent, subsumes, subsumed-by, and not-subsumed) as defined in the concept-subsumption-outcome value set. If the server is unable to determine the relationship between the codes/Codings, then it returns an error response with an OperationOutcome.

Usage note: every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification.
